Japan's island issues with its neighbors

Ya can stumble and fall with the rest...or read and heed from the best.

One major problem with the Chinese is they believe that territories and oceans that once belonged to their emperors of Ching Dynasty, Ming Dynasty, Tang Dynasty, Han Dynasty, etc. will always remain theirs.  The days of the empire are no more.  Not only that, but some groups who were forced to join the empire (ie Uygurs, Tibetans, etc.) still keep and maintained their separate language and culture that is clearly different from other Chinese.  In America, I have met 3 Uygurs and if you look at their appearance and language, you would think they fit better with Turkish than they do Chinese.  They can also speak perfect Chinese and understand our culture, but deep down, they know they are not.

What does the UN say on the ownership of these islands?

Currently, China and Japan are embroiled over a messy situation regarding territorial disputes.  Actually, they are fighting over uninhabited rocks, too small for human habitation to be considered islands.  it is more about nationalistic pride than anything else.  Chinese seeks some type of unsettled score with the Japanese because of WWII invasion and atrocities, while the Japanese remind the Chinese that they did not lose the WWII to Chinese or other Asians but only to America's atomic bombs.  They arrogantly resort they can easily defend themselves again if need be.  besides China, they have island dispute issues with South Korea (also an uninhabited one) and Russia (used to be inhabited by Japanese, but now occupied by Russians).
